摘要: Abstract The present work looks into the modification in spectroscopic and thermal behaviour of polyimide (PI), induced by 23 kGy dose 2 MeV electron. pristine irradiated polymers were characterised Fourier transform IR spectroscopy (FT-IR), thermogravimetric analysis (TGA) differential scanning calorimetry (DSC). Though emergence any new structures after irradiation was not observed, yet a decrease stability polymer accompanied melting temperature observed irradiation.
